CALCulate<n>:LIMit<k>:ACPower:ALTernate<ch>[:RELative] <LowerLimit>,
<UpperLimit>
This command defines the relative limit of the alternate channels. The reference value
for the relative limit is the measured channel power.
If you have defined an absolute limit as well as a relative limit, the R&S FPL1000 uses
the lower value for the limit check.

CALCulate<n>:LIMit<k>:ACPower:ALTernate<ch>:RESult?
This command queries the state of the limit check for the adjacent or alternate chan-
nels in an ACLR measurement.
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweep mode.
